The WikiNode project tries to link every wiki in the world together. Our "WikiNode" links to closely-related wiki (and their WikiNode links back).

If you want to talk about something that is not quite on-topic here at Open Circuits (say, "desktop PC case modding", or "embedded Linux programming"), our WikiNode helps you find another wiki where people love to talk about that exact topic. The corresponding WikiNode on each of those wiki helps people who want to talk about "open hardware" to discover this wiki.

Texas Instruments Embedded Processors Wiki - the official wiki at ti.com for discussing the MSP430 (a 16-bit, ultra-low power, mixed signal microcontroller), TI DSPs, the TI OMAP (used to run Linux in the "open source handheld" Pandora handheld game console, the Beagle Board, and the Gumstix Overo) and other ARM-based processors, and other TI processors.

RepRap Wiki - discusses the RepRap project to build a "Replicating Rapid-prototyper", a self-copying 3D printer. "Complete open-source instructions and plans are published on this website for zero cost and available to everyone so, if you want to make one yourself, you can."

EcoModder Wiki - discusses various ways to measure and improve vehicle gas economy, including "MPGuino is an open source fuel economy computer (Arduino based) for any vehicle with electronic fuel injection and a Vehicle Speed Sensor."

Open Component Project - a shared repository of public domain symbols, footprints, and 3D component models for use in electronic design automation (EDA) software.

Artists, inventors, scientists, engineers. The exciting thing to me is to learn about strange things that creative people are doing around the world, with no regard for genre, style, school of thought, area of expertise, etc. ... committed to the idea of "availability over promotion", meaning their main concern is to help things exist, rather than making hits or selling lots of copies.

Ballonboard Wiki - for the Balloon Project. They have developed a small single-board computer that can run Linux. Also discusses "The Balloon Open Hardware License (BOHL) ... The license is intended as a general purpose open hardware license".

2 Gumstix wiki: (Gumstix are motherboards that run Linux#Gumstix. Gumstix expansion board schematics and layouts open hardware -- published under a creative commons licence. )

Gumstix User Wiki - "Gumstix users can share their knowledge, showcase their Gumstix-based projects, and pass on links to other sources of information and materials." needs wikinode

emQbit Wiki(offline as of 2011-07-29, Internet Archive capture) - "The Free ECB_AT91 V1 is a Single Board Computer made by emQbit. You can download the specs and build your own." based on a 180 MHz ARM9 processor (Atmel AT91RM9200); runs Linux.

Arduino Playground - discusses the Arduino board based on the Atmel AVR ATmega168. (See also the Atmel AVR wiki).

ElphelWiki - discusses the free software and open hardware inside Elphel cameras. That hardware includes a FPGA that handles video processing and video compression, and a ETRAX FS processor that runs Linux.

The Great Internet Migratory Box of Electronics Junk - "a progressive lending library of electronic components. An internet meme in physical form halfway between P2P zip-archive sharing and a flea market. It arrives full of wonderful (and possibly useless) components, but you will surely find some treasures to keep. You will be inspired look through your own piles, such as they are, and find more mysterious components that clearly need to be donated to the box before it is passed on again." needs wikinode
